PISTONS ARE SUPPLIED COMPLETE WITH PISTON RINGS, WRIST PIN AND CIRCLIPS.

Transcription

1 Features Exact replacement, high silicon content aluminum alloy with the same content and weight. Eliminates the need to replace all pistons unnecessarily. Replace only the piston(s) required for the repair. Piston rings, bearings, wrist pins and circlips are all interchangeable with the OEM components. Makes repairs simpler, faster, and more economical. Sierra pistons do not require additional piston to cylinder wall clearance like competitor s forged units. This allows Sierra pistons to use standard break-in and warm-up procedures, not long and complicated procedures like the competition. No one warranties internal engine parts better than Sierra! That s because we re confident in our quality. Compare our quality, coverage and warranty to anyone and you will see why Sierra is the obvious choice for your next repair. ALL PISTONS ARE SUPPLIED COMPLETE WITH PISTON RINGS, WRIST PIN AND CIRCLIPS. 291

6 Bearings & Bearing Kits Contrary to popular belief, all bearings are not alike just because they have the same numbers stamped on them. There are many import bearings on the market today. The quality of the materials used and the tolerances in the manufacturing processes can have a dramatic effect on the life expectancy of the bearings. Sierra supplies only the highest quality bearings available to insure the integrity of your repair. Features Only premium quality. Available in convenient kits. b NEEDLE BEARINGS Std.
